Stop bashing on the dude..
You will most likely need to run a ground cable and a 12v + source up through the passenger A pillar up to the sunvisor. (to power up the monitor)
then run down the RCA cables for L and R audio and the yellow Video cable to PS3. (Do PS3s only run on HDMI?)
Then you need to power the PS3.

If you are only looking for power, then run a 12V line/or with a converter with whatever Volts you need for the monitor through:
fuse box->inline fuse->converter(voltage adapter)->A-pillar ->sun visor.
Same place can be used for AV cords as well.

I would recommend not to tap into the homelink wires. They are lower gauge wires and may not be suitable for you monitor. I'd rather run a slightly higher gauge wire with an inline fuse with lower rating.

There are empty slots in the fusebox. I used slot 4 or 5(I forgot) with an inline fuse, voltage converter and ran a ground cable to the a screw near the glovebox for my iPhone charger and aux purpose.

This setup will allow you to run your AV cables to the glovebox so you have minimal wire mess everywhere.

Be careful in running the wires through A pillars, DO NOT obstruct the air bag path.

Also, how are you planning on powering the PS3? inverter or something?

the ps3 im still thinking how to power it, temporarily i think ill connect it to my head unit. i had a friend with a similar setup. ill take what you said in consideration read up on it some more.

OP, it's nice of you to think about your passengers motoring experience.
I hardwired a monitor into my steering wheel.
(I know selfish right? )I just tapped into the horn wires, then I taped the horn down so that it was always on/hot...so that it could power up the monitors. Sure it was noisy with the horn masking the sound of the movies, but I found that wearing headphones to listen to the movies while driving around helped a bit.

The ideal set up would be a HUD projecting across your entire windshield, but that's a whole different thread.
